Have you ever played with a magnet and stuck it in a sandy wash? It will pick up lots of black stuff. Some call it black sand; some might think ...

paleomagnetic records show that the intensity drops by up to 90 percent in the process of pole-switching. We should all feel grateful that we live in a time of magnetic stability, because the field ...

the planet's magnetic field (the magnetosphere) channels these particles toward the poles, where the magnetic field lines converge. According to NOAA, the most recent geomagnetic storm will be ...

Global sea ice cover hit a historic low in February as the world endured exceptional heat, with temperatures near the North Pole soaring 11 degrees Celsius above average, Europe's climate monitor ...

Earth's magnetic north pole is on the move, prompting updates to the World Magnetic Model (WMM). This crucial tool for navigation ensures that satellites, aircraft, and even smartphone users can ...

Quadrupoles help to keep the particles in a tight beam. They have four magnetic poles arranged symmetrically around the beam pipe to squeeze the beam either vertically or horizontally. Dipoles are ...

If you’re on the health and fitness side of the internet—which, let’s face it, you probably are if you’re reading WH—you’ve definitely seen countless (and often contradictory) weight ...

Earth’s magnetic poles are constantly on the move, but they haven’t drifted far enough to actually flip in the modern age. Researchers know that Earth’s poles have flipped in the past ...

Geographic north, which is a straight line between wherever you are on the planet and the (geographic) North Pole, doesn’t actually point at the north magnetic pole at all. It’s a bit ...
